Support text messages

[piegamesde]

The protocol level on that one is rather easy. Implementation notes:

• Sender side:
  • Add a --text file to the send command (alternatively, have a send-text command?)
  • If the file to be sent is -, the content from stdin is sent as text message. Interactive prompts are disabled (though I don't think we have any at the moment).
  • Don't forget to limit the input size to something sensible.
• Receiver side:
  • Text messages are always accepted by default
  • Do some quick content type checking and maybe display binary files differently
  • Maybe filter terminal escape codes? (Also maybe sending colored text is a feature, but are there any security risks?)
  • Check text size again before printing (maybe automatically open $PAGER with the content on long messages?)
  • Add CLI flag to write the message to a file instead (optional IMO)

I would be interested in being able to receive text messages that were sent from the python client. Once in a while someone tries this and is presented with an unhelpful error message. This would probably be easiest to implement on top of the transfer-v2 API change once that is done, right?

Any updates on this? This feature would be really handy IMHO to send secrets e.g. passwords.
